Hey Martin, Thanks. I saw that the other day and it's just about dead on where it should be isn't it.

That one review we saw where the GTX was beating the PA at 47+cfm was a pretty accurate one.

There really amazing rad's, I've never really used any low cfm 120x25mm fans on one,well except playing around, but my 480 w/115 Pana in a push-pull can pull a 437W TEC at 21vdc and a high clocked chip and give me a 2.5C rad out to ambient delta, I'm guessing thats around a 5-600W heat dump easily, maybe more.

Hey I think you picked a good guy to carry on for you, from what I've seen of his testing he has a really good methodology and plays it straight down the line and lets the chips fall where they may. You have to have faith in your testers integrity or the results don't mean much, he's a good one.

Yeah, Skinnee's doing some great work. I'm just glad to see more radiator testing, it's been a pretty lacking area for a while. Some of the earlier rad tests from many years ago didn't try looking at multiple fans during testing, and that could leave you to believe one radiator was better for everything.

It's becoming more and more clear with tests like these, that there is no "Best" for everything, instead we have alot of VERY GOOD radiator options and they all tend to have their sweet spots.

This is really good stuff, hopefully he continues to enjoy and do us all this great service.

I love seeing new quality tests that validate a recent purchases. TFC on Scythe-Flex G's in the living room. GTX with San Aces in the garage.

Special thanks to Martin, Skinnee, and Vapor for quality (time consuming) testing. And you too, Ira, for consistent level-headed advice.

Waiting for my gtx360 in the mail, actually based my final decision on which to get following that chart.

Do people actually use 25mm fans on the GTX? IF so they really need to do their research. I see the relevancy on the low fin density rads...

This is the research. If you see anyone using low speed yates on a GTX, direct them here.

I'm glad to see it to, rad tests have always been my favorite.

I agree, a rad is just a tool, you need to match one to the fans your prefer using and the heat-load you'll have on it. To much has always been made of rad's, there a pretty simple little device, its just heat exchanger. Tailor it to your preference and the job it that it needs to do.

Yeah I hope he doesn't get burned out on testing, that's a lot of work. There are so many variables, and then the constant requests for more testing of the variables. No one can run all that down, you could spend a month just on one rad, or longer. It's just a good basic guideline, with a good tester anyway, people can play around with them from there and answer there own questions for a lot of it.

Same with block testing, 4 or 5 mounts for each block is tiring, but then if you really wanted to run it all the way down you would need to do a hard, medium and soft mount on each one (and all the pressures in between), of the re-mounts to really find the optimum pressure for that paticular block and mobo combo. I can get a .5C to a C or two just from the mounting pressures, not even counting the basic re-mount. Thats just something everyone has to do for themselves with there mobo and block, you can't expect a tester to do all that for them.

Thanks Patch....

Thanks Martin, Ira and others...I appreciate the kind words.

Testing does get a bit hectic at times...I just take a day or so break, then plow back into it. The amount I have learned since first setting up the test bench is incredible, I never expected to get so much out of providing the community with information...I see why Martin is hooked.

You hit the nail on the head with CPU block testing...there are just so many variables. For mount pressure, I'm playing it as equal as I can for all the blocks. I tighten them down to the point where I feel comfortable, I don't have a means to measure the amount of pressure on the CPU...but I do measure the thumbnight height of the hold-down plate to ensure all are "level". Sucks I can't be more precise on this piece of CPU block testing.

What I do wont make it any more of a precise measurement but may save you some time and help to make sure each mount is consistent. You may already do this.

I use a 3/8" thick piece of HDPE for a back-plate with 6-32 studs through it. If you make one of the studs a couple of inches longer then the other 3 it makes it a lot easier to stab the block onto the studs.

When I get the pressure that I want on the springs I run a nut with a washer on it up to the bottom of the mount on all the studs, then I run a lock nut up under that and using box end wrenches so that the top nut wont rise any higher I lock the second nut under the first.

Works pretty well for getting the same pressure each time. I still measure it with a steel rule each time to make sure its the same. It will usually stay that way for at least 4 or 5 mounts if I'm careful. That way once I've found the right pressure for block and mobo I can do some TIM remounts to work my temp's on down. It will generally take me two weeks or so to get my mount the way I want it, thats letting each mount run for a few days to see how it settles in.

On the mobo side of the back plate I use a rubber flat washer and a nut and waher to tighten the plate down to the mobo. I use a 1/8" piece of neoprene between plate and the back of the mobo to cusion it a little.

My block doesn't generally have bolt heads out the bottom of it, I just don't have its cold-plate on in this pic, with the cold-plate on they are flush, its a TEC block.
